Helicarriers are advanced flying command centers that double as aircraft carriers. Specifically, Helicarriers were designed to be capable of sustained, independently-powered flight, via four, massive turbine engines that provide the lift needed to keep them in the air, though they were able to retain seaborne capabilities. Their technology was created, in part, with designs by Howard Stark.

S.H.I.E.L.D. relied on Helicarriers as highly strategic mobile bases from which they could perform a number of effective reconnaissance, stealth deployment, or direct strike operations

The Strategic Homeland Intervention, Enforcement, and Logistics Division, better known by its acronym S.H.I.E.L.D., is an American extra-governmental military counter-terrorism and intelligence agency, tasked with maintaining both national and global security.
